Treatment compositions comprising low levels of an oligoamine

ABSTRACT

Treatment compositions that include relatively low levels of an oligoamine. Related methods of use and preparation.

FIELD OF THE INVENTION

The present disclosure relates to treatment compositions comprising lowlevels of certain oligoamines. The present disclosure further relates torelated methods of use and preparation of such compositions.

BACKGROUND OF THE INVENTION

Many treatment processes, such as laundry wash processes, are designedto eliminate soils from surfaces, such as fabrics. Some soils can causemalodors on fabrics, which may persist or even form after the treatmentprocess is finished. Thus, manufacturers of consumer products andindustrial cleaning products are continuously seeking to providecompositions and processes that provide improved malodor control.

Separately, certain polyamines or oligoamines are known to be used indetergent compositions. Such polyamines or oligoamines may facilitatecertain cleaning benefits, such as grease removal. However, at thelevels typically required to provide such benefits, the polyamines maycause discoloration, such as yellowing, on the target surface, such as afabric, for example due to reactivity of the polyamines or oligoamineswith various species on or around the fabric surface.

There is a need for improved treatment compositions that provide malodorbenefits, preferably without significant discoloration/yellowingproblems.

SUMMARY OF THE INVENTION

The present disclosure relates to treatment compositions that includecertain oligoamines at relatively low levels.

For example, the present disclosure relates to a treatment compositionincluding: from about 0.01% to about 1.0%, by weight of the treatmentcomposition, of an oligoamine and/or a salt thereof, where theoligoamine has a structure according to according to Formula I:

Where each L is independently —(C_(m)H_(2m))—, where the index m isindependently for each L an integer from 2 to 6, n is an integer from 1to 10, and each of R¹-R⁵ is independently selected from H and C₁-C₄alkyl, preferably where at least one of R¹-R⁵ is H; and an additionaltreatment adjunct.

The present disclosure also relates to a process of treating a surface,the process including the steps of: providing a surface, preferably afabric, more preferably a fabric soiled with sebum, and contacting thesurface with a composition according to the present disclosure,optionally in the presence of water.

DETAILED DESCRIPTION OF THE INVENTION

The present disclosure relates to treatment compositions that includelow levels of an oligoamine of a certain structure. It has been foundthat such oligoamines can provide surprising malodor benefits, forexample with regard to laundered fabrics.

Without wishing to be bound by theory, it is believed that metal ions,such as copper ions (e.g., Cu²⁺), in a treatment liquor can facilitatethe breakdown of certain soils, such as sebum, on a target surface. Suchbreakdown may release volatile, malodorous compounds into the air. It isbelieved that the oligoamines of the present disclosure can chelate andsequester copper ions in a treatment liquor, and thereby inhibit therelease of such malodorous compounds.

Furthermore, it has been found that the oligoamines of the presentdisclosure are effective at surprisingly low levels. The low oligoaminelevels are efficient with regard to cost and formulation space.Additionally, due to the low levels of oligoamine, the treated surfacesshow little to no discoloration or yellowing. As described above,oligoamines are known to provide certain cleaning benefits, butgenerally they must be formulated at higher levels to see such benefits.Thus, the manufacturer would have little reason to expect a meaningfulbenefit at such low levels of oligoamines according to the presentdisclosure.

Pouched compositions mayhave relatively low amounts of water, for example less than about 20%,or less than about 15%, or less than about 12%, or less than about 10%,or less than about 8%, by weight of the detergent composition, of water.

The oligoamine and additional treatment adjuncts of the presentdisclosure are described in more detail below.

Oligoamine

The treatment compositions of the present disclosure include anoligoamine or a salt thereof. Oligoamines according to the presentdisclosure comprise amine functions, which can be primary, secondary, ortertiary amines, connected through specific alkylene groups. Withoutwishing to be bound by theory, it is believed that oligoamines of thepresent disclosure are well-suited for chelating certain metals, such ascopper (Cu²⁺), and that such chelation may provide malodor controlbenefits.

The treatment compositions according to the present disclosure maycomprise relatively low levels of an oligoamine. As described above, ithas surprisingly been found that low levels of the present oligoaminesmay provide malodour-control benefits with minimaldiscoloration/yellowing negatives. The treatment compositions of thepresent disclosure may comprise from about 0.01% to about 1.0%, or toabout 0.75%, or to about 0.5%, or to about 0.4%, or to about 0.3%, or toabout 0.2%, or to about 0.15%, by weight of the treatment composition,of the oligoamine. For the purposes of the present disclosure, theweight percent of the linear oligoamine is calculated using the weightof the free base form.

The oligoamines of the present disclosure may be considered linearoligoamines By “linear,” it is meant that there are no furtheramine-containing side chains grafted on the oligoamine backbonerepresented by Formula I. However, it is understood that the linearoligoamine may, at least in some cases, have alkyl groups that areattached to oligoamine backbone, such as methyl or ethyl groups.

The oligoamines of the present disclosure may have a structure accordingto Formula I:

wherein

each L is independently —(C_(m)H_(2m))—, wherein the index m isindependently for each L an integer from 2 to 6, preferably m is 2 or 3,more preferably m is 2 (e.g., ethylene groups);

n is an integer from 1 to 10, preferably from 1 to 5 (i.e. triamines,tetramines, pentamines, hexamines, heptamines, etc.), more preferablyfrom 1 to 3, even more preferably from 1 to 2, most preferably 1; and

wherein each of R¹-R⁵ is independently selected from H and C₁-C₄ alkyl,preferably H and methyl (i.e., C₁ alkyl). It is understood that when nis greater than 1, each R⁵ is independently selected from the providedgroup, although each R⁵ may be identical.

The index m may be independently for each L an integer from 2 to 6,wherein the index m is 2 or 3, preferably 2, for each of two L groupsthat are directly connected to a common N atom. It is believed thathaving two such L groups adjacent to a common N atom will facilitateimproved metal sequestration, even if other L groups are relativelylarger (e.g., have m being greater than 2).

Each of R¹-R⁵ may be H. R⁵ may be methyl. R⁵ may be H. One or both of R¹and R³ may be methyl. R¹ and R³ may be methyl, and R² and R⁴ may both behydrogen. Each of R¹-R⁵ may be methyl. It may be preferred that at leastone of R¹-R⁵ is H, and even more preferred that at least one of R¹-R⁴ isH. R¹-R⁴ may be H, and R⁵ may be independently selected from H and C₁alkyl.

The present compositions may include an oligoamine having a structureaccording to Formula I above, wherein L, m, n, and R¹-R⁵ are defined asabove, with the proviso that if n is equal to 1, then R⁵ is selectedfrom H and a moiety having from 1 to 10 carbons, or from 1 to 6 carbons,or from 1 to 4 carbons.

Depending on the product type and/or overall benefit space desired, theformulator may select oligoamines having primary, secondary, and/ortertiary nitrogens, particularly at the terminal positions. Withoutwishing to be bound by theory, it is believed the presence of primarynitrogens in the present oligoamines may provide improved malodorcontrol benefits, believed to be due to improved chelation efficiencyand/or coordination to a target surface, such as a fabric. Also withoutwishing to be bound by theory, it is believed that tertiary nitrogens inthe present oligoamines may result in fewer interactions with othermaterials in the treatment composition, for example reactions withcertain perfume materials that may otherwise result in reactions (e.g.,Schiff base reactions) and consequent color changes in liquid products.

Treatment compositions comprising mixtures of various oligoaminesaccording to Formula I are also part of the scope of the presentdisclosure.

Suitable oligoamines according to the present disclosure may includediethylenetriamine (DETA), 4-methyl diethylenetriamine (4-MeDETA),dipropylenetriamine (DPTA), 5-methyl dipropylenetriamine (5-MeDPTA),triethylenetetraamine (TETA), 4-methyl triethylenetetraamine (4-MeTETA),4,7-dimethyl triethylenetetraamine (4,7-Me₂TETA), 1,1,4,7,7-pentamethyldiethylenetriamine (M5-DETA), tripropylenetetraamine (TPTA),tetraethylenepentaamine (TEPA), tetrapropylenepentaamine (TPPA),pentaethylenehexaamine (PEHA), pentapropylenehexaamine (PPHA),hexaethyleneheptaamine (HEHA), hexapropyleneheptaamine (HPHA),N,N′-Bis(3-aminopropyl)ethylenediamine, or mixtures thereof.

DETA may be preferred due to itslow molecular weight and/or relatively low cost to produce.

The oligoamine may comprise diethylene triamine (“DETA,” where m isequal to 2, n is equal to 1, and each of R¹-R⁵ is H), or a derivativethereof, including alkylated forms (e.g., where one or more of R¹-R⁵ isan alkyl group, such as methyl). The oligoamine may comprise at least80% or even at least 90% or even at least 95% by weight of theoligoamine of a form of diethylene triamine (DETA), even more preferablythe oligoamine consists of a form of diethylene triamine (DETA). Theoligoamine may be selected from: DETA; 4-methyl DETA; and mixturesthereof; preferably DETA (unalkylated diethylene triamine).

Depending on the finished product or wash solution pH, the nitrogenatoms may be protonated, partially or fully, resulting in the salt formof the oligoamine according to Formula I. These (partially) protonatedoligoamines are also considered as part of the scope of the presentdisclosure. It may be that when the oligoamine is in salt form, the saltis not a salt of an anionic surfactant.

The oligoamines of the present disclosure may have a molecular weight ofbetween about 100 to about 1200 Da, or from about 100 to about 900 Da,or from about 100 to about 600 Da, or from about 100 to about 400 Da,preferably between about 100 Da and about 250 Da, most preferablybetween about 100 Da and about 175 Da, or even between about 100 Da andabout 150 Da. For purposes of the present disclosure, the molecularweight is determined using the free base form of the oligoamine.

A skilled person in the art will know how to obtain oligoaminesaccording to the present disclosure. For example, oligoamines accordingto Formula I where L has m equal to 2 may be obtained by reactionsinvolving ammonia and ethylene dichloride, followed by fractionaldistillation. The common oligoamines obtained are diethylenetriamine(DETA), triethylenetetramine (TETA), and tetraethylenepentamine (TEPA).Other oligoamines according to Formula I may be formed, where m is equalto from 2 to 6 via use of the appropriate halogen-disubstitutedalkylenes.

Above the pentamines, i.e the hexamines, heptamines, octamines, andpossibly nonamines, the cogenerically derived mixture does not appear toseparate by distillation and can include other materials such as cyclicamines and particularly piperazines.

Suitable ethylene-based oligoamines according to the present disclosureare commercially available from multiple chemical suppliers includingDow, BASF, Huntsman, and Akzo Nobel Corporations.

Antioxidants may also help to reduce yellowing thatmay be associated with amines, allowing the amines to be formulated at arelatively higher level. Antioxidants are substances as described inKirk-Othmer (Vol. 3, page 424) and in Ullmann's Encyclopedia (Vol. 3,page 91).

The skilled artisan is able to makeinformed decisions regarding the selection of antioxidants to employ.

Whitening/Brightening Agent

The additional treatment adjuncts of the present disclosure may includea whitening or brightening agent. Such agents may be selected from ahueing agent, an optical brightener, or mixtures thereof. The use ofsuch agents may further reduce the effects of discoloration or yellowingand may enable formulation of the oligoamines at higher levels.

The compositions of the present disclosure may include a hueing agent.It has surprisingly been found that graft polymers according to thepresent disclosure may inhibit transfer of fugitive dyes, while havinglittle effect on the deposition and/or performance of hueing agents ontarget fabrics.

Hueing agents (sometimes referred to as hueing dyes, fabric shadingdyes, or bluing or whitening agents) typically provides a blue or violetshade to fabric. Such agent(s) are well known in the art and may be usedeither alone or in combination to create a specific shade of hueingand/or to shade different fabric types. The hueing agent may be selectedfrom any suitable chemical class of dye as known in the art, includingbut not limited to acridine, anthraquinone (including polycyclicquinones), azine, azo (e.g., monoazo, disazo, trisazo, tetrakisazo,polyazo), benzodifurane, benzodifuranone, carotenoid, coumarin, cyanine,diazahemicyanine, diphenylmethane, formazan, hemicyanine, indigoids,methane, naphthalimides, naphthoquinone, nitro, nitroso, oxazine,phthalocyanine, pyrazoles, stilbene, styryl, triarylmethane,triphenylmethane, xanthenes and mixtures thereof. The hueing agent maybe selected from an azo agent, a triarylmethane agent, atriphenylmethane agent, or mixtures thereof.

Suitable hueing agents include fabric shading dyes such as smallmolecule dyes, polymeric dyes, and dye-clay conjugates. Preferred fabricshading dyes are selected from small molecule dyes and polymeric dyes.Suitable small molecule dyes may be selected from the group consistingof dyes falling into the Colour Index (C.I., Society of Dyers andColourists, Bradford, UK) classifications of Acid, Direct, Basic,Reactive, Solvent or Disperse dyes.

C. Preparation of Malodor Test Fabrics Sixteen malodor test fabrics perwash load are prepared by applying 300 μl of Body soil malodorcomposition described in Table B to de-sized 2×5 inch white polycotton50/50 (PCW50/50) swatches. 48 grams of liquid detergent to be tested(see, e.g., Example 1, Table 1, below) is added to Duet 9200 washingappliance set to Normal cycle; 77° F. wash cycle followed by a 60° F.rinse cycle. Tap water is used, which contains an ambient level ofcopper, due to copper piping systems, for example. Malodor test fabricsare washed in 7 gpg wash water with 3.9 kg, 50×50 cm clean cotton andpoly-cotton ballast then dried in a Maytag double stack tumble drier setto low for 20 minutes. The dried fabrics are placed in a mylar bag andsealed for 24 hours.

D. Analytical Detection of Malodor on Fabric

The malodor reduction using ABS/Squalene malodor sensors arequantitatively determined by Gas Chromatography Mass Spectroscopy usingan Agilent gas chromatograph 7890B equipped with a mass selectivedetector (5977B), a Chemstation quantitation package and a Gerstelmulti-purpose sampler equipped with a solid phase micro-extraction(SPME) probe. Calibration standards of 6-Methyl-5-hepten-2-one (CAS110-93-0), Trans-2-heptenal (18829-55-5) and 3-methyl-2-Butenal(107-86-8) are prepared by dissolving a known weight of these materialsin light mineral oil (CAS 8020-83-5) (each material available from SigmaAldrich). Fabrics are cut into uniform 2 inch by 2.5 inch pieces andplaced in 10 mL headspace crimp vials. Vials are equilibrated greaterthan 12 hours before analysis. The following settings are used in theauto sampler: 80 C incubation temperature, 90 min incubation time,VT32-10 sample tray type, 22 mm vial penetration, 20 min extractiontime, 54 mm injection penetration and 300 s desorption time. Thefollowing settings are used for the Front Split/Splitless inlet helium:split mode, 250 C temperature, 12 psi pressure, 79.5 mL/min total flow,3 mL/min septum purge flow, 50:1 split ratio and 22.5 min GC run time.The follow settings are used in the oven: 40 C initial temperature, 12C/min heating program, 250 C temperature and 5 min hold time. Based onthe partition coefficients (K at 80 C) of each component, the totalnMol/L liter of 6-Methyl-5-hepten-2-one (K=3353), Trans-2-heptenal(K=3434), and 3-methyl-2-Butenal (K=1119) are calculated.

These values of these three measurements (in nmoles/L) are addedtogether to provide the Total ABS/Squalene Markers (nmoles/L) for agiven test leg.

E. % Malodor Reduction Oxidation Products Calculations

The % Malodor Reduction Oxidation Products is provided as a percentagecomparing the reduction of the amount of selected malodor markers asprovided by the test composition compared to the (nil-oligoamine)reference composition. The value is determined as follows:

% Reduction OxidationProducts=(Markers_(ref)−Markers_(test))×100/Markers_(ref)

Values for Markers_(ref) and Markers_(test) are defined as follows:Markers_(ref)=Total ABS/Squalene Markers (nmoles/L) of the fabricswashed with the formulation without oligoamine (e.g., the reference orcontrol formulation)Markers_(test)=Total ABS/Squalene Markers (nmoles/L) of the fabricswashed with the formulation with the tested oligoamine

As the measured oxidation products are typically considered malodorous,it is believed that the greater the % reduction of oxidation productsprovided by a composition, the less malodorous the treated fabrics arelikely to be. Therefore, greater values of % Malodor Reduction OxidationProducts are typically preferred. The compositions and processes of thepresent disclosure may provide a % Malodor Reduction Oxidation Productsvalue of at least about 10%, or at least about 20%, or at least about30%, or at least about 40%, or at least about 50%, or at least about60%, or at least about 70%, or at least about 80%.

Whiteness Loss Test Method Test

The following procedures are followed to test for whiteness losses(e.g., ΔWI).

A. Preparation of Whiteness Test Fabrics

De-sized Cotton, Polycotton and Polyester whiteness test fabrics can beordered from WFK. (WFK Testgewebe GmbH, Christenfeld 10, D-41379Bruggen, Germany). Four of each fabric type (12 fabrics total) areprepared for the whiteness test by washing them four times in 48 grams(750 ppm) of Tide Free and Clear and 25 grams (390 ppm) Downy Free rinsein a Kenmore Top Loader set to Normal wash cycle, 77 F wash, 60 F rinse,7 grains per gallon. An initial whiteness reference measurement is madeusing Konica Minolta spectrophotometer and reported as Initial WhitenessIndex CIE. The Whiteness Index CIE value is a common index of whitenessand refers to measurements made under D65 illumination, the standardrepresentation of outdoor daylight. For a perfect reflecting,non-fluorescent white material, the CIE Whiteness would be 100. Intechnical terms, whiteness is a single number index referencing therelative degree of whiteness of near-white materials under specificlighting conditions. The index has been devised such that most peoplewill agree that the higher the whiteness index, the whiter the material.

B. Whiteness Test

Fabrics are placed in a 7.57 liter custom washing tub under theconditions summarized in Table 3 below. Fabrics are washed with 5.65grams (746 ppm) of detergent (liquid TIDE®) in the wash cycle togetherwith background soil, followed by 3 grams (396 ppm) liquid fabricsoftener (DOWNY® Free) in the rinse cycle. Once the rinse cycle iscomplete, all the fabrics are removed and placed in a tumble dryer. Thisis repeated for 10 wash, rinse and dry cycles. After 10 cycles, fabricsare measured for whiteness loss using a Konica Minolta spectrophotomerand the measurement is reported as Final Whiteness Index. An averagedelta WI (i.e., ΔWI), representing the difference in the whiteness indexmeasurements between the initial and treated, is calculated for eachfabric tested, and represented by the following calculation: ΔWI=InitialWhiteness Index after preparation—Treated Whiteness Index after 10-20cycles. Typically, ΔWI is a negative value as the whiteness tends todecrease after washing with background soil. The whiteness index isreported in the table as ΔΔWI=ΔWI test with oligoamine—ΔWI REF (niloligoamine). ΔΔW is a negative value if the whiteness tends to decreaseafter washing with a test liquid detergent composition containing aoligoamine compared to a reference liquid detergent composition thatdoes not contain an oligoamine. Numbers close to zero would represent anoligoamine which has little impact on fabric yellowing.

The results shown in Table 5 illustrate the malodor prevention ontextiles washed in liquid compositions containing linear oligoamine ofthe present disclosure in a composition according to Example 1A comparedto similar detergent without linear oligoamine, even when the amine ispresent in the composition at levels at or below 0.1 wt %, and/or in thetreatment liquor at levels below 4 ppm, or even below 3 ppm.

Example 6. Oligoamine and Antioxidant

To show the malodor control benefits of oligoamines of the presentdisclosure, including in combination with antioxidant, a liquiddetergent composition according to Example 1A in Example 1, Table 1above is provided. Various combinations of a linear oligoamine andantioxidant are added to the liquid detergent composition in the levelsprovided in Table 6. The antioxidant added to Examples 6D and 6E is ahindered phenol antioxidant (specifically, octadecyl3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate, sold commercially asTinogard TS (ex BASF)).

The compositions are tested for % Reduction Oxidation Products accordingto the test method provided above. Results are shown in Table 6.

As shown in Table 6, the presence of the DETA amine results in improvedmalodor control. The data in Table 6 further shows that the testedcombination of an oligoamine according to the present disclosure and anantioxidant provides improved malodor control.

Notably, although the level of DETA is the same in Liquid Compositions6B and 6E, Liquid Composition 6E (which further comprises antioxidant)provides almost twice the percentage of oxidation products removal.Further, the performance of Liquid Composition 6E is on par with theperformance of Liquid Composition 6C, which comprises twice as much ofthe DETA amine.

Example 7. Effects of Alkylation

To show the effects that various degrees of alkylation of the presentlydescribed oligoamines can have on malodor reduction benefits, thefollowing molecules are tested at the provided levels according to thetest method provided above. The tests are run in a North Americanfront-loading automatic washing machine.

The percentage reduction of oxidation products vs. the referencecomposition are provided for each compound below in Tables 7A and 7B.

As shown in Table 7B, Example 7F provides the relatively greatestmalodor reduction.

Example 8. Oligoamine Vs. Whiteness

To show the effect that oligoamines (and % levels thereof) can have onwhiteness, certain amines are added to North American liquid TIDE® (acommercially available heavy duty liquid laundry detergent) as providedin Table 8. Various fabrics (cotton, polycotton, and polyester) aretreated under North American conditions for ten wash cycles with thecompositions.

After ten cycles, whiteness losses are determined according to theWhiteness Loss Test Method, as provided above in the Test Methodssection. Results are provided in Table 8. Negative numbers showwhiteness losses, with numbers of greater magnitude indicating greaterwhiteness losses (e.g., −10 indicates more whiteness loss than −5). Itis preferred that the whiteness losses are between 0 and −5, or between0 and −4. Whiteness losses that are greater in magnitude indicate thatthe product may be less preferred for consumer use.

TABLE 8 Cotton Polycotton Polyester ΔΔWI ΔΔWI ΔΔWI Trial Amine (wt %) vsREF vs REF vs REF 8A — 0.0 0.0 0.0 (REF: TIDE ®) 8B 0.094% DETA −4.5−4.7 −3.9 8C 0.04% N,N′-Bis −3.0 −5.7 −3.7 (3-aminopropyl)ethylenediamine 8D 1.2% DETA −16.5 −19.5 −19.2

As shown in Table 8, the presence of amines may result in whitenesslosses upon multiple treatments. However, the whiteness losses providedby amine levels of, e.g., less than 0.1 wt % (see Trials 8B and 8C) arerelatively acceptable to a manufacturer. By way of comparison, Trial 8D,which includes DETA levels of above 1%, shows whiteness losses that arebelieved to be less preferred. It is believed that alkylated oligoaminesmay further improve whiteness losses and/or allowing the oligoamines tobe formulated at relatively higher levels while keeping whiteness losseswithin an acceptable range.
